Fabrication MethodLaser/Wire Cut, Stamped
MaterialStainless Steel/Inconel
Process TechnologyBurnishing, Peening
Equipment TypeRoll Burnisher

Solution

Bel Air Finishing recommended a Roll Burnisher as the optimal solution to improve the fatigue performance of stainless steel springs. This advanced burnishing process utilizes the pressure and rolling action of precision polishing balls to compact and harden the surface, enhancing resistance to wear, fatigue, and corrosion. Unlike traditional methods, this technique eliminates the “orange-peel” effect and delivers a smooth, uniform finish without damaging delicate components.

By automating the burnishing process, the Roll Burnisher increased the lifespan and performance of the springs while reducing manual labor and ensuring consistent, high-quality results. This reliable and efficient solution meets the stringent demands of hardware applications, preparing the springs for long-term performance under challenging conditions.
